The default order for sorting packages found using find_package(). It can assume one of the following values:
Natural sorting can be employed to return the highest version when multiple versions of the same library are found by find_package(). For example suppose that the following libraries have been found:
By setting NATURAL order we can select the one with the highest version number libX-1.2.10.
set(CMAKE_FIND_PACKAGE_SORT_ORDER NATURAL)
find_package(libX CONFIG)
The sort direction can be controlled using the CMAKE_FIND_PACKAGE_SORT_DIRECTION variable (by default decrescent, e.g. lib-B will be tested before lib-A).
